Detailed Description
The following describes specific embodiments of the present invention in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.
The traction machine and the driving system thereof according to the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of a tractor according to an embodiment of the present invention, fig. 2 is a schematic structural view of a rotary driving member 10 according to an embodiment of the present invention, and fig. 3 is a block structural view of a driving system according to an embodiment of the present invention.
The traction machine of the present embodiment includes a traction wheel assembly 70 and a drive system including:
a rotary drive member 10 drivingly connected to the traction wheel assembly 70;
A driving control device (not shown in the figure) electrically connected with the rotary driving member 10 and used for controlling the start and stop of the rotary driving member 10;
An energy storage device 30 storing energy and comprising a first energy storage mechanism and a second energy storage mechanism, both electrically connected to a drive control device configured to:
judging whether the traction wheel assembly 70 is in an operating state;
When traction wheel assembly 70 is in an operational state, the first energy storage mechanism and/or the second energy storage mechanism are controlled to power rotary drive 10.
The traction sheave assembly 70 of the tractor is capable of pulling or releasing a rope to effect transport of wires, cables, traction ropes, and the like. Traction wheel assembly 70 is driven by a drive system that includes rotary drive 10 (e.g., an electric motor), energy storage device 30, and a drive control device (e.g., an electric motor drive controller). The rotary driving member 10 is in driving connection with the traction wheel assembly 70, the energy storage device 30 stores energy and is used for supplying energy to the rotary driving member 10, and the driving control device is electrically connected with the rotary driving member 10 and can control the start and stop of the rotary driving member 10. The energy storage device 30 includes a first energy storage mechanism and a second energy storage mechanism, each of which is capable of separately or simultaneously powering the rotary drive member 10 to cause the rotary drive member 10 to rotate to operate the traction wheel assembly 70. The first and second energy storage mechanisms of the present invention directly power the rotary drive 10 with lower energy losses and lower noise than conventional high power diesel engines that drive the traction wheel assembly 70 via a hydraulic system.
In one embodiment, the first and second energy storage mechanisms are a battery module 31 and a range extending mechanism 32, respectively. The battery module 31 can store electric energy, and can directly supply the electric energy to the rotary driving member 10, and can recover the energy when the motor passively rotates. The range extender 32 may be a diesel engine, a gasoline engine, a hydrogen energy engine, etc. The range extender 32 can provide additional electrical energy to extend the duration of the rotary drive 10 or to increase the electrical power input to the rotary drive 10. By adopting the battery module 31 and the range-extending mechanism 32 as the components of the energy storage device 30, compared with the combined driving of a high-power diesel engine and a hydraulic system, the structure provided by the embodiment of the invention is more energy-saving and environment-friendly, has lower noise and optimizes the working environment of the tractor.
In one embodiment, the drive control device comprises a drive module 21 electrically connected with the battery module 31 and the range-extending mechanism 32, wherein the drive module 21 is used for acquiring the power requirement of the rotary driving piece 10 and sending a power requirement signal, and a main control module 22 electrically connected with the drive module 21 and used for controlling the on-off between the battery module 31 and the drive control device and the on-off between the range-extending mechanism 32 and the drive control device according to the power requirement signal. The main control module 22 is a control center of the tractor, the driving module 21 can be electrically connected with the battery module 31 and the range extending mechanism 32, and can acquire the power requirement of the rotary driving member 10, send the power requirement to the main control module 22, and the main control module 22 can control the battery module 31 and/or the range extending mechanism 32 to supply power to the rotary driving member 10 according to the power requirement. By adopting the driving control device, the battery module and the range extending mechanism 32 can be started in a targeted manner according to the power requirement of the rotary driving piece 10, so that energy can be saved, and the phenomenon that the traction wheel assembly 70 cannot normally rotate due to insufficient power of the rotary driving piece 10 can be prevented.
In one embodiment, as shown in fig. 4, a schematic diagram of an energy supply mode of a driving system according to an embodiment of the present invention is provided. The main control module 22 is further configured to determine a driving load of the rotary driver 10 according to the power demand signal, obtain a remaining power of the battery module 31, control the battery module 31 to individually supply energy to the rotary driver 10 when the remaining power of the battery module 31 is greater than a first preset power threshold and the driving load is less than a preset load threshold, control the battery module 31 and the range-extending mechanism 32 to simultaneously supply energy to the rotary driver 10 when the remaining power of the battery module 31 is greater than a second preset power threshold and the driving load is greater than the preset load threshold, and control the range-extending mechanism 32 to individually supply energy to the rotary driver 10 when the remaining power of the battery module 31 is greater than the second preset power threshold and the driving load is less than the first preset power threshold and the range-extending mechanism 32 to individually supply energy to the rotary driver 10 when the remaining power of the battery module 31 is less than the second preset power threshold.
The main control module 22 can determine the driving load of the rotary driving member 10 according to the power demand signal transmitted from the main control module 22, and the main control module 22 can also determine the power supply mode of the driving system according to the magnitude of the driving load and the remaining power of the battery module 31. When the driving load of the rotary driving member 10 is large, the battery module 31 and the range-extending mechanism 32 are required to simultaneously supply power to the rotary driving member 10, otherwise, the power of the rotary driving member 10 is insufficient, and the rotary driving member 10 cannot work normally. When the electric quantity of the battery module 31 is smaller than a certain electric quantity value, the main control module 22 of the present invention can preferably adopt the range-increasing mechanism 32 to supply power to the rotary driving member 10, so as to keep the electric quantity of the battery module 31 in a higher state, and prevent the battery from failing to work due to insufficient electric quantity when the load of the rotary driving member 10 is higher, thereby causing the rotary driving member 10 to fail to work normally. When the electric quantity of the battery module 31 is greater than a certain electric quantity value, the main control module 22 of the present invention can preferentially adopt the battery module 31 to supply power to the rotary driving member 10, because the battery module 31 is more energy-saving and has lower noise than the range-increasing mechanism 32. The first preset power threshold is greater than the second preset power threshold, when the power of the battery module 31 is greater than the first preset power threshold, the remaining power of the battery module 31 is in a more sufficient state, when the power of the battery module 31 is less than the first preset power threshold and greater than the second preset power threshold, the remaining power of the battery module 31 is in an insufficient state, and when the power of the battery module 31 is less than the second preset power threshold, the battery module 31 is in a power shortage state or a state incapable of discharging operation.
Specifically, as shown in fig. 4, when the driving load is greater than the first preset load threshold, the battery module 31 and the range-extending mechanism 32 are required to simultaneously supply power to the rotary driving member 10 to satisfy the power demand of the rotary driving member 10. In case that the driving load is smaller than the first preset load and the power of the battery module 31 is larger than the first preset power threshold, the rotary driving member 10 is individually powered by the battery module 31. The required power corresponding to the first preset load threshold is the maximum discharge power of the battery module, and the required power corresponding to the second preset load threshold is the maximum output power of the range-extending mechanism 32. When the remaining power of the battery module 31 is smaller than the first preset power threshold and the driving load is smaller than the second preset load threshold, the range-extending mechanism 32 drives the rotary driving member 10 while charging the battery module 31. When the remaining capacity of the battery module 31 is smaller than the first preset capacity threshold and the load is zero, the range extending mechanism 32 outputs energy to charge the battery module 31. When the remaining capacity of the battery module 31 is smaller than the first preset capacity threshold and the driving load is equal to the second preset load threshold, the range extending mechanism 32 alone drives the rotary driver 10. When the battery module 31 charge is less than the second preset load threshold and the drive load is greater than the second preset load threshold, the tractor stops working.
In one embodiment, the tractor further includes a human-machine interaction module 40 electrically connected to the main control module 22, the main control module 22 further configured to obtain control commands input by the human-machine interaction module 40, and adjust the energy supply of the rotary drive member 10 according to the control commands. In some special cases, the energy supply mode of the rotary driving member 10 needs a specific energy supply mode, so the tractor provided by the embodiment of the invention further includes a man-machine interaction module 40 electrically connected with the main control module 22, the man-machine interaction module 40 can transmit a user instruction to the main control module 22, and the main control module 22 can adjust the energy supply mode of the driving system according to the control instruction after acquiring the control instruction input by the man-machine interaction module 40. For example, the noise generated when the battery module 31 is powered is smaller than the noise generated when the range-extending mechanism 32 is powered, and when the user is working in a residential area, the user needs to keep a quiet environment, and the user controls the driving mechanism through the man-machine interaction module 40 to always power the rotary driving member 10 by using the battery module 31.
In one embodiment, as shown in FIG. 3, the drive system further includes a power management module 50 electrically coupled to the drive module 21, the power management module 50 being configured to convert and transfer energy generated by the first and second energy storage mechanisms into the drive module 21. The power management module 50 is capable of converting energy transmitted from the first energy storage mechanism and the second energy storage mechanism and transmitting the converted energy to the drive module 21. For example, the first energy storage mechanism is a battery module 31, the second energy storage mechanism is a range extender 32, the rotary driving member 10 is a motor, the driving module 21 is a motor driving module 21, and the power management module 50 can adjust the electric energy transmitted by the battery module 31 and the range extender 32, so that the voltage and the current of the adjusted electric energy can be safely transmitted to the motor driving module 21. By adopting the power management module 50, energy transmitted by the first energy storage mechanism and the second energy storage mechanism can be converted and transmitted, so that the energy transmission process of the tractor is safer and smoother.
In one embodiment, as shown in fig. 2, the rotary drive 10 further comprises a speed reducer 11 and a brake 12 coaxially and drivingly connected to the speed reducer 11, and the drive system further comprises an auxiliary hydraulic module 60 for controlling braking or release of the brake 12. The traction machine needs braking during traction and after traction is completed, the brake 12 can be coaxially and drivably connected with the speed reducer 11 of the rotary driving member 10, and the rotary driving member 10 can be braked when the brake 12 stops rotating. The brake 12 is controlled by the auxiliary hydraulic module 60, and the main control module 22 can be electrically connected to the auxiliary hydraulic module 60 and send control signals to the auxiliary hydraulic module 60, and can control the brake 12 to brake or release when the auxiliary hydraulic module 60 receives the control signals. With the adoption of the driving system, the traction wheel assembly 70 can be braked or released in time, so that the traction machine can brake and release more in time.
In one embodiment, as shown in fig. 5, a schematic hydraulic schematic diagram of an auxiliary hydraulic module 60 is provided according to an embodiment of the present invention. The auxiliary hydraulic module 60 includes a main pump 61, the main pump 61 supplies oil to the brake 12 through an oil supply passage, a multiple-way valve 62 is further provided on the oil supply passage, and a brake valve 63 is provided on an oil passage between the multiple-way valve 62 and the brake 12.

By adopting the auxiliary hydraulic module 60, the brake 12 can be controlled through the hydraulic oil circuit, the control mode is reliable and efficient, and the arrangement of the auxiliary hydraulic module 60 can enable the braking moment when the brake 12 executes braking to be more stable.
